7.07 is the so-called "catcher's balk", wherein the pitcher has not committed a balk, but is charged with one anyway due to illegal action by the catcher.

Five cents, please.

I disagree. FWIW, if I, or any real non-internet umpire I come across says "catcher's balk", we are referring to 4.03a. And FWIW, I can't recall 7.07 ever happening in a game I umpired or watched.
